SHEETLPILING.

To yall whom t mayoonoern Be it known that I, GEORGE B. HoAe, a citizenof the United States, a resident of Cleveland, county of Cuyahoga, y ofOhio, have invented a new and useful Improvement in Sheet-Filings', ofwhichthe following is a specification, the princlpleof the inventionbeing' herein explained and the best mode in which I have contemplatedapplying that principle, so as to distinguishit from other inventions.

My invention relates to sheet-piling, and has for its object theprovision of sheet'- piling elementsv which when assembled will` form atight sheet suiliciently impervious to water and quicksand for practicaluse and 1n which each element is of light Weight, cheap in constructionand durable, so as to be oa-f4 pable of continued and indenite use.

My said invent-ion consists of means hereinafter fully described andparticularly'setI y showing the contiguous earth. Fig. 3 is a horizontalsection, on an enlarged scale, 'of a fragmentary portion of the piling.

Each element of the illustrated piling embodying my invention co prisesa main or body portion A; made prferably of wood plankingof the usualcharacter, and two facing-strips B and C. One of these strips, B, ismade of channel steel, and is secured to one of the two opposite sidesof smaller dimension, by means of spikes or screws D passing throughsuitable countersunk openings b, with the ianges b and b of the channelprojecting outwardly. `The other ofthe two strips, C, is of segmentalcrosssection, and is secured to the other of said two opposite faces bymeans of spikes or screws also passing through 'countersunk openingsl c,with the curved side of the strip upon the outside, as shown.

The facing-strips of similar cross-section are, of course, all made ofmaterial having the same dimensions, and the segmental Specification ofLetters Patent.

Application iled June 4, 1912. Serial No. 701,531.

strips are preferably of such dimensions that vwhen laid in thechannels,- they will simultaneously engage the web and flanges of thelatter, as shown in Fig. 3.

In assembling the piling, the elements are laid so. that a strip C willengage a strip B in the manner above described. In thus obtaining threelines of contact, a joint is obtained which will practically excludewater 'and quicksand, which is the desired end to be obtained. Thedimensions 'of the strips C may, however, be made such that they envgage only the flanges, and I have found that the two lines of contactthus secured, in some cases, answer the purpose. Continued use may,inthis last described form, eventually, wear the twoengaging strips sothat three lines of contact will ultimately be obtained.

While other forms of facing-strips may be used without departing fromthe spirit of my invention, I find the luse of channels and segmentalstrips rmit me to take advantage of 'material o` stock form or standardcross-section and size, a ircumstance which materially contributes tothe cheapness of my construction without in any way de reciating itspractical value.

yurthermore, my above described form of piling, on account of the use ofwood for the body-portion, is of minimum weight, consistent with therequired strength, and hence may be handled with facility and economy.

Having fully described my invention',

what I claim and desire to secure by Let- 'j ters Patent is:

1. A sheet-piling element consisting of a wooden strip of substantiallyrectangular crossLsection and having seoured respectively upon the Vtwoopposite sides, metal facing-strips, one of the latter being offacing-strlps, one of the latter having achannel-like cross-sectionandthe other having a segmental cross-section.

3. In sheet-piling, the combination of two adjacent sheet-pilingelements each of whose main or body portions is formed of wood, andwhose contiguous sides are provided lrespectively with a channelfacing-strip and wooden strip of substantially rectangular1Across-section andy having secured on one of the two opposite sides afacing-'strip of channel l.formation with the flanges projectingoutwardly; and upon the other of said two faces, afacing-strip of suchform as is adaptedy to simultaneously engage, when laid in saidchannelqstrip, both flanges of the latter. v i v 5. A sheet-pilingelement consisting of a wooden strip of substantially rectangularcross-section, and having secured on one of the two opposite sides afacing-strip of channel formation with lthe anges projecting outwardly;and upon the other sidebf 'said two faces a 44facing-strip of such formas is adapted to .simultaneously engage, when laid in saidchannel-strip, the web and bot-h flanges of the latter.`

Signed by me this 28th day of May, 1912.
